Honda Accord collision warning problems

Filed Oct 29, 2026 · Driver assistance · CA

I was driving steadily on the freeway in slow moving traffic at 20-30 miles and had a lot of distance between me and the car in front. There was a sudden jolt and it appeared the vehicle was attempting to brake unexpectedly. If my foot had not been on the accelerator, I believe the vehicle could have come to a sudden, complete stop, potentially causing the vehicle behind me to rear end my car. Several months, before this incident, the Collision Mitigation Braking System and Lane Assist warning alerts would sound while I was driving on the freeway. This happened at two separate times. The sudden alarms are startling, and I cannot safely read the dashboard messages while driving. I am forced to slow down or pull over to check what is wrong, creating additional safety risks. I have a scheduled appointment with the Dealer this weekend due to the sudden braking however, I've brought this issue up with the service department in the past with the warning lights and they don't seem to have a definitive answer as to what is causing it. I have less than 20,000 miles on this vehicle.

In XXX, the driver assistance and safety systems on my 2025 Honda Accord SE began failing repeatedly. While driving, warning messages would appear for the collision mitigation braking system, lane keeping assistance, adaptive cruise control, and automatic high beams, and these systems would become unavailable. This happened multiple times over XXX and XXX . I took the vehicle to Hugh White Honda in [XXX], four to five times for this problem. The dealer replaced the forward-facing camera twice under warranty, but the warnings and system failures continued after each repair. The dealer was never able to identify or fix the underlying cause. I filed a complaint with American Honda on XXX (case XXX). Because the safety systems on a nearly new vehicle could not be repaired, I traded the vehicle in on XXX, with approximately 17,000 miles. No crash or injuries occurred, but the vehicle repeatedly lost the use of its collision avoidance and lane keeping safety systems in normal driving, and the manufacturer could not repair the defect.

I am reporting repeated, unpredictable loss of engine power and propulsion in my 2019 Honda Accord Touring 2.0T (approximately 146,000 miles). The exact cause remains UNKNOWN. On XXX, while driving on [XXX] near [XXX], my vehicle suddenly lost acceleration at highway speeds and eventually stalled. The vehicle repeatedly lost power, experienced crank-no-start conditions, and at one point could barely maintain 10 mph. I was stranded and had to have the vehicle transported to a Honda dealership in [XXX]. Diagnostic code P0087 (Fuel Rail/System Pressure Too Low) was recorded multiple times, including at 70–74 mph. Numerous warnings appeared, including emissions, brake system, electric power steering, stability assist, adaptive cruise control, collision mitigation, and road departure mitigation. The unpredictable loss of propulsion creates a serious collision risk, especially on highways and in traffic. The Honda dealership initially could not reproduce the failure. After replacing the spark plugs at my expense, the vehicle was returned to me. Approximately 23 miles later, the malfunction returned, and I immediately brought the vehicle back without clearing any codes. Honda subsequently diagnosed and replaced the high-pressure fuel pump at my expense, but the loss-of-power issue continued. The vehicle previously received Honda’s in-tank fuel pump safety recall repair in May 2025. Despite that recall remedy and subsequent repairs, the vehicle continues to malfunction. The exact cause remains undetermined. The vehicle has been inspected by an authorized Honda dealership. Repair records and diagnostic information are available, and the vehicle can be made available for inspection upon request. I am requesting an investigation into this recurring safety-related loss of propulsion. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my Honda on a highway at approximately 65 mph after rainfall, I experienced a serious and potentially life-threatening safety failure. Without warning, the steering wheel suddenly became locked/restricted, making it extremely difficult to control the vehicle. At the same time, numerous warning lights and safety-system warnings appeared, including: - Brake system warning - Electric Power Steering (EPS) warning - Vehicle Stability Assist warning - Hill Start Assist warning - Adaptive Cruise Control warning - Lane Keeping Assist warning - Collision Mitigation Braking System warning - Road Departure Mitigation warning This incident occurred while I was traveling approximately 65 mph on the highway and nearly caused me to lose control and crash. The sudden loss/restriction of steering control combined with the simultaneous failure or disabling of multiple driver-assistance and safety systems created an extremely dangerous situation. The fact that this occurred after driving in rainy/wet conditions is also concerning. I have researched this issue online and found numerous reports from other Honda owners describing similar warning lights, steering/electric power steering problems, and multiple safety-system failures, particularly involving Honda Accord vehicles. I am extremely concerned that this may represent a recurring safety-related defect rather than an isolated incident. A steering system that can suddenly become locked or severely restricted while a vehicle is traveling at highway speed presents a serious risk of a crash, injury, or loss of life. I respectfully request that the federal safety agency investigate this issue, review complaints involving similar Honda vehicles, and determine whether there is a common defect involving the electric power steering system, electrical system, water intrusion, or communication between the vehicle's safety-control modules. This problem needs to be investigated before someone is seriously injured or killed.Best regards.

1-The Supplemental Restraint System (SRS) / active collision avoidance system failed. Warning lights are actively displayed on the dashboard indicating that the SRS and collision mitigation systems are disabled/malfunctioning. The vehicle is parked and available for inspection upon request 2- Because the SRS / collision safety system is completely non-functional, the primary driver and passengers are operating a vehicle where airbags and active restraint systems may fail to deploy during a crash, presenting an immediate safety risk on public roads. 3-Yes. The safety defect was identified, but the selling dealership refused to provide assistance or perform the necessary repairs to resolve the active safety defect. 4-The vehicle issue was reported directly to the selling dealership, but they failed to complete repairs. Additionally, a formal complaint has been filed and opened with the State DMV Vehicle Safety Complaint Unit to investigate the unroadworthy condition of the vehicle. 5-SRS and collision system warning indicators appeared on the dashboard. Upon inspecting repair options, the vehicle warranty company confirmed that SRS/collision system components are strictly excluded from coverage, leaving an unaddressed safety defect. 1. Attempted Warranty Repair: Contacted the extended warranty provider, who formally denied coverage because SRS and collision systems are excluded under the policy terms. 2. Contacted Selling Dealership: Reached out directly to the dealership to address the unroadworthy SRS safety fault; the dealer remained non-responsive and failed to resolve the issue. 3. Escalated to State DMV: Opened an official case with the state DMV Vehicle Safety Complaint Unit regarding the selling of a vehicle with an active, unaddressed SRS safety defect. 4. Escalated to Financing Lender (Credit Acceptance): Sent formal notice to the auto loan holder requesting assistance or escalation; the lender refused to assist

My 2016 Honda Accord Touring has an intermittent failure of multiple Honda Sensing safety systems. The vehicle displays warnings for Collision Mitigation Braking System, Road Departure Mitigation System, Adaptive Cruise Control, and Lane Keeping Assist System. When this occurs, these driver-assistance and collision-avoidance features become unavailable. This is a recurring problem. In August 2023, an authorized Honda dealer diagnosed substantially similar symptoms. The technician documented DTC P2583-87, described on the repair order as “lost comm with the wave radar.” The dealer removed the bumper, tested wiring between the radar and camera, checked radar power and ground, and diagnosed a faulty millimeter-wave radar unit. The Honda dealer replaced the radar assembly with part 36802-T2A-A05 and performed radar aiming/calibration. The repair order states that normal operation was restored. I paid $1,422.08 for the repair and related charges. The problem has now returned and is intermittent. At times all systems work normally; at other times the multiple Honda Sensing warnings appear together and the safety systems become unavailable. I am concerned that a previously replaced and calibrated Honda millimeter-wave radar/safety system has experienced a recurring failure. I am requesting that the federal safety agency review this issue and similar complaints to determine whether a safety-related defect exists.

Sudden braking; car comes to a complete stop and brakes so Hard. Most likely fault from Collision Mitigation Brakking system

Since I purchased this car in 2022, the collision mitigation braking system has randomly engaged for no reason. This has happened multiple times over the years, day and night, when no other vehicle, road obstructions, or other factors warrant the system triggering.

I own a 2019 Honda Accord Sport 1.5T. While operating my vehicle, multiple safety-system warnings appeared on the dashboard at the same time. The vehicle displayed “Brake Hold System Problem,” “Adaptive Cruise Control System Problem,” “Collision Mitigation Braking System Problem,” and “Road Departure Mitigation System Problem,” each instructing me to see my dealer. These warnings concerned me because they involved the braking system and several Honda Sensing safety systems simultaneously. I parked the vehicle and turned the engine off. When I restarted the vehicle, all of the warnings had disappeared and the dashboard appeared normal again, even though no repair had been performed. The vehicle has approximately 72,980 miles. I have photographs documenting the warnings while they were displayed. I am reporting this to the federal safety agency because the problem was intermittent and affected multiple braking and driver-assistance systems at the same time. I am concerned that the systems could malfunction again while driving, including the braking/collision-mitigation system. I would like this incident documented as a potential safety defect involving the 2019 Honda Accord.
